FAQ
Hi All,
Does anyone do a benchmark to verify the index writing efficiency of lucene?
When the index size is larger than 10G, will it be much slower than smaller
ones ?

Actually i did some works about this issue,
and i found that, if build small index firstly then merge them all, the time
taken will significantly decline.

Hi Yonik,
How does Solr deal with this issue, does it just leave this problem to
lucene?


Thanks,

Eric

    You can increase the merge factor to get fewer merges,
    or you can set maxMergeDocs or setMaxMergeMB to prevent merging of any
    segments above a certain size and them call optimize at the end.

    Solr leaves it to Lucene.
